RECOMMENDATORY NOTICES. 



OPINION OF THE RIGHT REV. CHAS. P. McILVAINE, D. D. 



Bishop of the Protestant Episcopal Churchy Diocese of Ohio ; President of 

 Kenyan College^ Sfc. 



Kenyon College, Gambler, Ohio, Feb. 1842. 

 Messrs. Turner &, Fisher: 

 Gentlemen, — On reacliing- home, afiter a long absence, I had the pleaf;ure 

 of reciving the copy of the work prepared by Dr. Ruschenberger on Physi- 

 ology and Animal Mechanism, for the use of schools. If my opinion of its 

 merits can be of any service to its circulation, I am free to say that not only 

 are the subjects of the work such as ought to enter into the course of study 

 of the higher classes of our schools, but this work seems to me to be well 

 adapted to the want of .schools in reference to its subjects. At any rate, I 

 know not a better for its professed purposes. 



Yours, very truly, and respectfully, 



CHAS. P. McILVAINE. 



OPINION OF THE HON. LEVI WOODBURY, 



United States Senator from New Hampshire. 



Washington, 28th Jan, 1842. 

 Messrs. Turner & Fisher. 

 Gentlemen, — Yours of the 22d inst, has been received, with the First and 

 Second Book on Natural History, which you have recently published. 



I have examined them with some care and appreciate the plan of commu- 

 nicating the elements of this interesting branch of science in so cheap and 

 clear a form. 



With my best wishes for the success of your enterprise, 



I am, respectfully, 



LEVI WOODBURY. 



OPINION OF THE HON. DANIEL STURGEON, 



United States Senator from Pennsylvania. 



Senate Chamber, Washington City, Jan. 29th, 1842. 

 Messrs. Turner & Fisher. 

 Gentlemen. — I have examined with some care the two small volumes you 

 were so kind as to send me. 



I think Dr. Ruschenberger has- succeeded in condensing into as small a 

 space as possible, much valuable information on the subject of which he 

 treats, and think the work admirably calculated to impart general knowledge 

 on this interesting subject. 



I will be pleased to see it adopted in our high schools and colleges as a 

 text book. 



With sentiments of respect and esteen), yours, 



DAN'L STURGEON. 



OPINION OF THE HON. SAMUEL L. SOUTHARD, 



United States Senator from New Jersey. 



Washington, Feb. 15th, 1842. 

 Messrs. -Turner & Fisher. 

 Dear Sirs, — I am gratified by your kindness, in sending me the two 

 voltimes referred to, in your letter of the 31st of January. I entirely concur 

 in the objects you desire to accomplish. Few things can be more important 

 to our common country. My incessant and inexorable duties, have, thus far, 

 prevented me from making that examination of the volumes which I desire. 

 I am respectfully, &c. &c. 



SAMUEL L. SOUTHARD.
